Robert is not convinced by Dave Wood:
David, or anyone else out there, can you say more about “the really vast data base from up to 50 years of multi-locational trials carried out as a matter of course by CGIAR institutes. “? There is some data (for about 10 years) on the CIMMYT website for wheat and maize. It is a bit difficult to understand and access; but it is something. What about the other crops and centers?
Well? The ball is now officially in Dave’s court.
